Cookies are small, usually randomly encoded, text files that help you navigate through a website. They are generated on the sites that you visit, as well as by third-parties that websites work with, to manage key elements of their business-user functionality. In most cases they do not involve or use personal information in any way.
Cookies are used extensively online and have become part of the fabric and make-up of what has made the internet work effectively for consumers and businesses. Without cookies, many areas of functionality (for example, user logins, shopping baskets and other customization features) would not work as expected.
